Accordingly, those of ordinary skill in the art will recognize that various modifications, equivalents, and/or alternatives on the various example embodiments described herein may be variously made without departing from the scope and spirit of the disclosure. With regard to description of drawings, similar components may be marked by similar reference numerals.

In the disclosure, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate existence of corresponding features (e.g., components such as numeric values, functions, operations, or parts) but do not exclude presence of additional features.

In the disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included.

The terms, such as “first”, “second”, and the like used in the disclosure may be used to refer to various components regardless of the order and/or the priority and to distinguish the relevant components from other components, but do not limit the components.

Prior to describing the disclosure in detail, a structural form of an example electronic device to which various embodiments of the disclosure may be applied will be described with reference to FIGS. 1A to 4. However, it will be understood that the example electronic devices to which the disclosure may be applied are not limited to the examples illustrated in FIGS. 1A to 4 below.

FIGS. 1A and 1B are diagrams illustrating a front display area of an example electronic device according to an embodiment. In FIG. 1A, an electronic device 100 may be understood to be in a state in which a first structure 110 is in a closed state with respect to a second structure 120, and in FIG. 1B, the electronic device 100 may be understood to be in a state in which the first structure 110 is in an open state with respect to the second structure 120.

Referring to FIGS. 1A and 1B, the electronic device 100 may include the first structure 110 and the second structure 120. For example, the first structure 110 may be arranged to be reciprocatable by a specified distance with respect to the second structure 120 in a direction{circle around (1)} as shown.

According to various embodiments, the electronic device 100 may include a display 111 arranged on a front surface 1001 of the first structure 110. According to an embodiment, the display 111 may include a front display area 1111 that is at least partially exposed through the front surface 1001 of the first structure 110. According to an embodiment, the electronic device 100 may include at least one key button 112 and/or 113 arranged on at least one of a left or right side surface. According to an embodiment, the at least one key button 112 and/or 113 may be arranged to be exposed to a side surface of the electronic device 100 and/or to protrude from the side surface. According to an embodiment, the at least one key button 112 and/or 113 may include, for example, and without limitation, the power button 112 or the volume control button 113. According to an embodiment, the electronic device 100 may include at least one speaker module 114 arranged on one side surface. In various embodiments, the at least one speaker module 114 may be arranged in various areas except for an arrangement area of the display 111 as well as one side surface of the electronic device 100.

According to various embodiments, the electronic device 100 may include a rollable module (e.g., a roller comprising various structural elements such as, for example, and without limitation, a multi joint rail, or the like) 130 arranged at the boundary of the first and second structures 110 and 120. According to an embodiment, the rollable module 130 is rotatably arranged between the first and second structures 110 and 120 corresponding to the reciprocating motion of the first structure 110 in the direction{circle around (1)}. According to an embodiment, the rollable module 130 may include an inner support member 132, at least a portion of which may be exposed to the side surface of the electronic device 100, and a multi-joint module 131 arranged on an end of the inner support member 132 in a rolling form. According to an embodiment, the multi joint module 131 may move together when the first structure 110 reciprocates with respect to the second structure 120 in the direction{circle around (1)}, thereby guiding the display 111.

According to various embodiments, when the electronic device 100 is transitioned to the open state as the first structure 110 moves by the specified distance in the direction{circle around (1)} with respect to the second structure 120, the front display area 1111 of the display 111, which is exposed to the front surface 1001, may be expanded by an area EA having a specified area.

FIGS. 2A and 2B are diagrams illustrating a rear display area of an example electronic device according to an embodiment. In FIG. 2A, the electronic device 100 may be understood to be in a state in which the first structure 110 is in the closed state with respect to the second structure 120, and in FIG. 2B, the electronic device 100 may be understood to be in a state in which the first structure 110 is in the open state with respect to the second structure 120.

Referring to FIGS. 2A and 2B, the electronic device 100 may include the second structure 120 that is relatively movably arranged to the reciprocating motion of the first structure 110 described above to a rear surface 1002. According to an embodiment, the electronic device 100 may include a rear display area 1112 that may be visible through a through-hole 140 formed in the second structure 120. For example, the rear display area 1112, which is at least a part of the display (e.g., 111 of FIG. 1A) of the electronic device 100, may be an area extending from the front display area (e.g., 1111 in FIG. 1A) of the display 111. In other words, although the electronic device 100 includes the front and rear display areas 1111 and 1112 on the front surface (e.g., 1001 of FIG. 1A) and the rear surface 1002, the front and rear display areas 1111 and 1112 may be areas implemented when a single display 111 is arranged in the form of being rolled from the front surface 1001 to the rear surface 1002 inside the electronic device 100. According to an embodiment, when the first structure 110 is maintained in the closed state with respect to the second structure 120, the entire area DA1 of the rear display area 1112 may be implemented as a screen display area for displaying an arbitrary screen. Correspondingly, when the first structure 110 moves by a specified distance d1 with respect to the second structure 120 to be maintained in the open state, the area DA2 excluding the area corresponding to the movement of the first structure 110 of the specified distance d1 from the entire area DA1 may be implemented as the screen display area. However, the screen display area on the rear display area 1112 is not limited to the one described above and may be implemented as areas of various positions or areas depending on the design of the electronic device 100 (e.g., the location of the through-hole 140, the moving distance of the first structure 110, and the like) or the setting of a user.

According to various embodiments, the rear display area 1112 may have a width w3 that is smaller than that (e.g., w1 of FIG. 1A) of the front display area 1111. According to an embodiment, referring to FIGS. 2A and 2B, the electronic device 100 may include a printed circuit board arranged in an upper end internal area of the first structure 110 and at least one electronic component (e.g., an antenna, a microphone, a speaker, an input/output interface connector port, various sockets, an ear jack assembly, or the like) arranged in a lower end internal area of the second structure 120. In addition, the electronic device 100 may include an electrical connecting member (e.g., a flexible printed circuit board) that supports electrical connection between the printed circuit board and the at least one electronic component, and the electrical connecting member may be arranged in an area (e.g., a peripheral area PA1 and/or PA2 of the through-hole 140) avoiding the through-hole 140.

FIG. 3 is an exploded view illustrating an example electronic device according to an embodiment. An electronic device 300 described with reference to FIG. 3 may be at least partially the same as or similar to the electronic device 100 described above in FIGS. 1A, 1B, 2A, or 2B.

Referring to FIG. 3, the electronic device 300 may include a first structure 310 including a first plate 311. The first plate 311 may include a first surface 3111 and a second surface 3112 facing the first surface 3111. According to an embodiment, the electronic device 300 may include a second structure 320. For example, the second structure 320 may include a second plate 321 facing the second surface 3112 of the first plate 311, a first side wall 3211 extending perpendicularly from one side end of the second plate 321, a second side wall 3212 perpendicular to the first side wall 3211 and the second plate 321, and a third side wall 3213 perpendicular to the first side wall 3211 and the second plate 321 and parallel to the second side wall 3212. According to various embodiments, the second plate 321, the first side wall 3211, the second side wall 3212, and the third side wall 3213 may comprise the second structure 320 together with an opening 3214 for receiving at least a portion of the first structure 310.

According to an embodiment, the electronic device 300 may include a display 330 (e.g., a flexible touch screen display) which extends across at least a portion of the first surface 3111 of the first plate 311 and is interposed between the second surface 3112 of the first plate 311 and the second plate 321 through the first side wall 3211 of the second structure 320. According to an embodiment, the electronic device 300 may include a rollable module 360 for slidably connecting the first plate 311 and the second plate 321 and for guiding the movement of the display 330 interposed through the first side wall 3211 of the second structure 320.

According to various embodiments, the first structure 310 may reciprocate into the open and closed states with respect to the second structure 320 in the direction{circle around (1)} parallel to the second plate 321 and the second side wall 3212. Thus, the first structure 310 may be located at a first distance from the first side wall 3211 of the second structure 320 in the closed state and may be located at a second distance, which may be relatively larger than the first distance, from the first side wall 3211 in the open state.

According to various embodiments, the display 330 may include a planar portion 331 and a bendable portion 332. For example, the planar portion 331 may extend across at least a portion of the first surface 3111 of the first plate 311, and the extended portion may be mounted on the first surface 3111. The planar portion 331 may have a first width w1 in the direction{circle around (2)} perpendicular to the direction{circle around (1)}. For example, the bendable portion 332 may extend from the planar portion 331 to a space between the first side wall 3211 of the second structure 320 and the first structure 310 in a state that the first structure 310 is closed. According to an embodiment, when the first structure 310 transitions from the open state to the closed state, a first portion 3321 of the bendable portion 332 facing the second plate 321 may have a second width w2 that may be relatively shorter than the first width w1 in the direction{circle around (1)}. According to an embodiment, at least one region (e.g., the first portion 3321) of the bendable portion 332 may be exposed through the opening 3214 formed in the second plate 321. For example, when the first structure 310 is in the closed state with respect to the second structure 320, a screen display area 3323 included in the bendable portion 332 may be located at a position corresponding to the opening 3214 of the second plate 321, thereby exposing at least a portion through the opening 3214. According to an embodiment, the screen display area 3323 may have a third width w3 substantially similar to a through-hole 351 of a window cover 350 arranged on the rear surface of the second structure 320, where the third width w3 may be implemented to be shorter than the second width w2. According to an embodiment, when the first structure 310 is transitioned from the closed state to the open state, a second portion 3322 of the bendable portion 332, which is viewed from above the first plate 311, may be drawn by a specified length from the space between the first side wall 3211 and the first structure 310 to form a substantially plane between the planar portion 331 and the first side wall 3211 of the second structure 320.

According to various embodiments, the first plate 311 of the first structure 310 may include a battery mounting portion (e.g., a bracket). The battery mounting portion may include, for example, an opening 3113 for compensating for a volume change due to the swelling phenomenon of the battery.

According to an embodiment, the electronic device 300 may include a front support member 334 which is arranged between the first plate 311 and the planar portion 331 of the display 330 to support the planar portion 331 of the display 330. In other words, the front support member 334 may be arranged above the battery mounted on the battery mounting portion of the first plate 311. In an embodiment, one surface of the front support member 334 may be bonded to the display 330 in a bonding or taping scheme, and another surface may be fixed to the first surface 3111 of the display 330 in a screw, bonding or taping scheme, but the disclosure is not limited thereto.

According to various embodiments, the window cover 350 for shielding the opening 3214 formed in the second structure 320 may be arranged in one area of the second plate 321 of the second structure 320. According to an embodiment, the window cover 350 includes the through-hole 351 (e.g., a substantially transparent or translucent window) having a size corresponding to the screen display area 3323 included in the bendable portion 332 of the display 330. For example, when the first structure 310 is in the open state, the window cover 350 may include a translucent material such that the interior of the electronic device 300 is not visible. According to an embodiment, a touch sensor 352 for detecting a user input (e.g., a touch, a drag, a press, hovering, or the like) may be arranged in an area corresponding to the through-hole 351. For example, a connector 3521 of the touch sensor 352 may be connected to a circuit portion 333 of the display 330. The touch sensor 352 may be electrically connected to a printed circuit board 341 through a connector 3331 connected to the circuit portion 333 of the display 330.

According to various embodiments, a rear window 312 may be arranged on the second surface 3112 of the first plate 311 in such a manner that at least a portion thereof overlaps the second plate 321. According to an embodiment, the electronic device 100 may include at least one electronic component arranged in a space between the rear window 312 and the first plate 311. In various embodiments, the at least one electronic component may include at least one of the printed circuit board 341, a receiver 343, a speaker 344, a sensor module 345 (e.g., an illuminance sensor, a proximity sensor, an infrared sensor, an ultrasonic sensor, a fingerprint recognition sensor, a facial recognition sensor, an iris recognition sensor, or the like), a card tray 347, or at least one key module 348 and/or 349 (e.g., a power key module 348 and/or a volume control key module 349).

According to various embodiments, the rollable module 360 may include a sub-support member 364 fixed to the second plate 321, an inner support member 361 arranged to be rotatable (or slidable) with respect to each other between the sub-support member 364 and the second surface 3112 of the first plate 311, a roller 365 formed on an end of the inner support member 361 to have a length corresponding to the first side wall 3211 of the second structure 320 and arranged to be rotatable, a multi-joint module 366 for guiding the rear surface of the display 330 under the guidance of the roller 365, a pair of first rails 362 arranged between the inner support member 361 and the sub-support member 364, and a pair of second rails 363 arranged between the inner support member 361 and the second surface 3112 of the first plate 311. According to an embodiment, the first and second rails 362 and 363 may be arranged to induce the inner support member 361 to perform a sliding movement relative to the sub-support member 364 and the first plate 311. According to an embodiment, the multi joint module 366 may include a plurality of unit multi-bars, and the plurality of unit multi-bars may be connected to each other to interwork with each other, thereby being bent along an outer peripheral surface of the roller 365. According to an embodiment, the bendable portion 332 of the display 330 may be guided in such a manner that the bendable portion 332 is rolled (or bent), such that an end of the bendable portion 332 is fixed to the sub-support member 364 arranged between the second surface 3112 of the first plate 311 and the second plate 321. According to an embodiment, the electronic device 300 may include at least one actuator 367 arranged between the inner support member 361 and the sub-support member 364 and/or between the inner support member 361 and the first plate 311. For example, the at least one actuator 367 may provide a continuous pressing force in a direction in which the first structure 310, which is opened or closed in sliding manner from the second structure 320, is opened or closed based on a certain bent portion.

According to various embodiments, the electronic device 300 may include an antenna module 380. For example, the antenna module 380 may be arranged on the first side wall 3211 of the second structure 320. According to an embodiment, the antenna module 380 may include a radiation pattern 381 arranged inside the first side wall 3211, a flexible printed circuit board 382 extending from the radiation pattern 381 to an area adjacent to the printed circuit board 341, and a connector 383 arranged on an end of the flexible printed circuit board 382. In various embodiments, the radiation pattern 381 may be arranged inside the first side wall 3211 in the form of a laser direct structuring (LDS), a thin film antenna (TFA), a flexible printed circuit board (FPCB), a steel use stainless (SUS), or the like, but is not limited thereto. According to an embodiment, the flexible printed circuit board 382 of the antenna module 380 may be arranged avoiding the through-hole 351 of the window cover 350. In an embodiment, the flexible printed circuit board 382 of the antenna module 380 may be electrically connected to a sub flexible printed circuit board 384 arranged on the sub-support member 364 in an area adjacent to the printed circuit board 341. The sub flexible printed circuit board 384 may be electrically connected to a wireless communication circuit through a coaxial cable 385 electrically connected to a wireless communication circuit (e.g., an RFIC) of the printed circuit board 341. In this regard, the radiation pattern 381 may be electrically connected to the wireless communication circuit on the printed circuit board 341 through the flexible printed circuit board 382 of the antenna module 380, the connector 383 of the antenna module 380, the sub flexible printed circuit board 384, the coaxial cable 385, and the printed circuit board 341. According to an embodiment, because the sub-support member 364 to which the sub printed circuit board 384 is fixed moves correspondingly when the first structure 310 is opened or closed, the coaxial cable 385 may be formed of a material having an excellent bending property. Alternatively, the coaxial cable 385 may be replaced with a flexible printed circuit board implemented with an excellent bending property material.

According to various embodiments, the circuit portion 333 of the display 330 may be at least partially fixed to the sub-support member 364. The connector 3331 extending from the circuit portion 333 of the display 330 may be electrically connected to the printed circuit board 341 fixed to the connector 3521 of the touch sensor 352 or the first plate 311 based on an electrical connection member 370. According to an embodiment, because the distance between the circuit portion 333 of the display 330 fixed to the sub-support member 364 and the printed circuit board 341 is changed corresponding to the opening and closing of the first structure 310, the electrical connection member 370 may include a flexible printed circuit board having an excellent bending or stretching property to correspond to the distance change.

FIG. 4 is an exploded view illustrating another structure of some components of an example electronic device according to an embodiment, and FIGS. 5A and 5B are diagrams illustrating an example camera device of an example electronic device according to various embodiments. An electronic device 400 described with reference to FIG. 4 may be at least partially the same as or similar to the electronic device 100 described above in FIG. 1A, 1B, 2A, or 2B, or the electronic device 300 described in FIG. 3, and may include other embodiments for at least some components.

Referring to FIGS. 4 and 5A, the electronic device 400 may include a camera device 490 which is rotatably arranged in an inner space of the electronic device 400 to photograph an image forward (e.g., an upward direction based on a first structure 410) and rearward (e.g., a downward direction based on a second structure 420) of the electronic device 400. For example, the camera device 490 may be arranged on an inner support member 461 of a rollable module 460 which slides with respect to a second surface 4112 of a first plate 411 based on a second rail (363 of FIG. 3), and may move in a direction corresponding to the sliding movement of the inner support member 461. In this operation, at least a part of the camera device 490 may be engaged with a multi-joint rail 468 arranged in at least one area of the inner support member 461, and may move in the direction of motion of the inner support member 461 while being rotated at a specified rotation amount.

According to an embodiment, the camera device 490 may include a shaft 491 whose one end is connected to one area of the inner support member 461, a gear 493 through which the shaft 491 passes, and a camera module 495 arranged on an opposite end of the shaft 491 to be coupled with the gear 493. According to an embodiment, the shaft 491 may be moved corresponding to the sliding movement of the inner support member 461, and the gear 493 may be pulled in accordance with the movement of the shaft 491 and may be rotated on the multi-joint rail 468 in engagement with the multi joint rail 468. Thus, the camera module 495 coupled to the gear 493 may be rotated by the amount of rotation of the gear 493 and the location of a lens 497 may be changed (e.g., rotated). Although the camera module 495 including the single lens 497 is illustrated in FIG. 5A, according to various embodiments, the lens 497 may be implemented as a plurality of lens. For example, as illustrated in FIG. 5B, depending on the manufacturing specification (e.g., dual camera mount) of the electronic device 400, the camera module 495 may include a plurality of lenses 497 a and 497 b.

According to an embodiment, when the first structure 410 is maintained in the closed state with respect to the second structure 420, at least one component arranged over the camera device 490 located at a first position may include an aperture of a specified size to support the angle of view of the lens 497 facing in front of the electronic device 400. For example, the first plate 411 of the first structure 410 may include an aperture 431 in an area corresponding to the first position of the camera device 490, and a front support member 434 arranged over the first plate 411 may also include an aperture 435 corresponding to the first position of the camera device 490. According to an embodiment, a planar portion 431 of a display 430 arranged over the front support member 434 may be structurally improved in an area corresponding to the first position of the camera device 490 to support a front view angle of the lens 497, and it will be described later.

Similar to the above description, when the first structure 410 is kept in the open state with respect to the second structure 420, at least one component arranged below the camera device 490 located at the second position may include an aperture to support the angle of view of the lens 497 facing rearward of the electronic device 400. For example, a second plate 421 of the second structure 420 may include an aperture 422 in an area corresponding to the second location of the camera device 490, and a window cover 450 arranged below the second structure 420 may also include an aperture 453 in an area corresponding to the second position of the camera device 490. According to various embodiments, the apertures 431, 435, 422 and 453, which are formed on at least one component arranged over the camera device 490 located at the first position and at least one component arranged below the camera device 490 located at the second location, may be formed to have a size capable of exposing the lens 497 to an outside, depending on whether the lens 497 is single or plural.

FIG. 6 is a diagram illustrating a position change form of a camera device according to an embodiment. The enlarged region in FIG. 6 may be understood as an internal cross-section with respect to one side (e.g., the right side with respect to the front side (1001 of FIG. 1A) of the electronic device 400) of the electronic device 400.

Referring to the description of FIG. 3, the sub-support member (364 of FIG. 3) of the rollable module (360 of FIG. 3) may be fixed to the second plate (321 of FIG. 3) of the second structure (320 of FIG. 3) in at least one area, and may be movable below the inner support member (361 in FIG. 3) of the rollable module 360 in the direction{circle around (1)}. For example, both ends of the sub-support member 364 may be fastened to a pair of first rails (362 in FIG. 3) fixed to both ends of the inner support member 361 in a screw scheme, and may be movable in the direction{circle around (1)} along the first rail 362. In this case, the inner support member 361 may move in the direction{circle around (1)} by sliding motion corresponding to the movement of the sub-support member 364. For example, the inner support member 361 may be fastened to a pair of second rails (363 of FIG. 3) fixed to both ends of the first plate (311 in FIG. 3) of the first structure (310 of FIG. 3) and moves along the second rail 363 in the direction{circle around (1)} corresponding to the movement of the sub-support member 364 by an external force.

Referring to FIGS. 3, 5A and 6 in connection with the above description, an external force (e.g., a physical force by a user body holding the electronic device 400) for opening the first structure 410 may be applied to the second structure 420. In this case, as the sub-support member (364 of FIG. 3) connected to the second plate (321 in FIG. 3) of the second structure 420 moves along the first rail (362 of FIG. 3) fixed to the inner support member 461 of the rollable module 460, the second structure 420 may move in the direction{circle around (3)}. In addition, the inner support member 461 of the rollable module 460 may move in the direction{circle around (3)} along the second rail (363 in FIG. 3) fixed to the first plate (311 in FIG. 3) of the first structure 410, corresponding to the movement of the second structure 420 in the direction{circle around (3)} (alternatively, corresponding to the movement of the sub-support member 364 connected to the second plate 321 of the second structure 420). In an embodiment, the movement of the inner support member 461 in the direction{circle around (3)} may pull the multi-joint rail 468 arranged in one area of the inner support member 461 in the direction{circle around (3)}. In this case, the multi joint rail 468 pulled in the direction{circle around (3)} may be engaged with the gear (493 of FIG. 5A) of the camera device (490 of FIG. 5A) connected to the inner support member 461 to rotate the gear 493. Accordingly, the camera module 495 coupled with the gear 493 of the camera device 490 may be rotated by the amount of rotation (or rotational motion) of the gear 493 on the multi joint rail 468 to change the position of the lens 497. For example, the rotation of the camera module 495 may change the position of the lens 497 toward the second structure 420.

Similar to the above description, when the external force for closing the first structure 410 opened acts on the second structure 420, the second structure 420 may move in the direction{circle around (4)}. The inner support member 461 may move in the direction {circle around (4)} along the second rail 363 fixed to the first plate 311 of the first structure 410, corresponding to the movement of the second structure 420 in the direction{circle around (4)}. In an embodiment, the multi joint rails 468 arranged on the inner support member 461 may be pulled in the direction{circle around (4)} corresponding to the movement of the inner support member 461 in the direction{circle around (4)}. In this operation, the gear 493 of the camera device 490 may be rotated while being engaged with the pulled multi-joint rail 468, and may rotate the camera module 495 fastened to the gear 493. The rotation (or the rotation amount) of the camera module 495 may change the position of the lens 497 included in the camera module 495 toward the first structure 410.

Based on the above description, when an external force for opening the first structure 410 acts on the second structure 420, the sub-support member (364 in FIG. 3) of the rollable module 460 and the inner support member 461 may move in the direction of {circle around (3)} along the first rail (362 in FIG. 3) and the second rail (363 in FIG. 3), respectively, so that the second structure 420 may move in the direction{circle around (3)}. In this case, the first structure 410 and the second structure 420 may have positional relationship that the first structure 410 moves relatively in the direction{circle around (4)} as the second structure 420 moves in the direction{circle around (3)}. Alternatively, when an external force for closing the first structure 410 acts on the second structure 420, the sub-support member 364 and the inner support member 461 of the rollable module 460 may move in the direction{circle around (4)}, along the first and second rail 362 and 363, respectively so that the second structure 420 may move in the direction{circle around (4)}. In this case, the first structure 410 and the second structure 420 may have positional relationship that the first structure 410 moves relatively in the direction{circle around (3)} as the second structure 420 moves in the direction{circle around (4)}.

According to various embodiments, a camera device cover 498 for containing at least a part of the camera device 490 connected to the inner support member 461 may be included in an area of the inner support member 461. For example, the camera device cover 498 may receive an internal hardware component (e.g., the camera module 495, a portion of a shaft (491 of FIG. 5A), a gear (493 of FIG. 5A), or the like), and the internal hardware component may be shielded from an outside to block foreign substances such as dust, and the like from flowing thereinto. According to various embodiments, the camera device cover 498 may include an aperture through which a part of the shaft 491 of the camera device 490 passes, and a peripheral portion of the shaft 491 passing through the aperture may be sealed with a separated adhesive material or the like.

FIG. 7A is a perspective diagram illustrating a front surface 4001 of an example electronic device according to an embodiment. FIG. 7B is a cross-sectional view taken along line A-A′ of FIG. 7A. FIG. 7C is a diagram illustrating a front display area of an example electronic device according to an embodiment.

Referring to FIGS. 7A and 7B, the electronic device 400 may mount the camera device 490 in an internal area thereof. In an embodiment, the camera device 490 may be arranged to overlap at least partially with the inner support member 461 which is slidably arranged in a lower area with respect to a front surface 4001 in the direction {circle around (1)}. For example, the camera device 490 may be arranged to allow the shaft 491 to be connected to one area of the inner support member 461 and the gear 493 to be engaged with the multi joint rail 468 arranged in the inner support member 461.

In an embodiment, the camera device 490 may be located at a first position P1 on the multi joint rail 468 when the electronic device 400 (or the first structure (410 of FIG. 6)) is kept in the closed state. In addition, the camera device 490 may be arranged such that the lens 497 of the camera module 495 faces the front surface 4001 of the electronic device 400 at the first position P1. In other words, in the closed state of the electronic device 400, the gear 493 of the camera device 490 may be arranged to be engaged with the multi-joint rail 468 such that the camera device 490 is located at the first position P1 and the lens 497 of the camera module 495 faces the front surface 4001, which may be implemented in the manufacturing process of the electronic device 400. In this regard, at least one component (e.g., the first plate (411 of FIG. 4) and/or the front support member (434 of FIG. 4), and the like) may include an aperture (e.g., the aperture (413 of FIG. 4) formed in the first plate 411 and/or an aperture 435 formed in the front support member 434) for supporting the angle of view of the lens 497 of the camera module 495.

Referring to FIG. 7C, a first area 10 corresponding to the first position P1 in a front display area 4111 of the display 430 arranged above the camera device 490 may be at least partially improved to support the angle of view of the lens 497. For example, a first gate line 31 or a first data line 41 of the display 430 arranged in the first area 10 may be implemented in a shape of a straight line, and at least a portion of a second gate line 33 or a second data line 43 may be implemented in shape of a curved line. In other words, the portion of the second gate line 33 or the second data line 43 arranged in a second area 20 related to the angle of view of the lens 497 may be provided in a shape of a curved line to avoid the lens 497. Alternatively, a portion of the display 430 corresponding to the first area 10 may be removed by U-cut or punching. For example, the conductive line of the display 430 including a gate line 30 b or 30 c and a data line 40 b or 40 c may be designed to be at least partially bent in the peripheral area of the lens 497 not to overlap with the lens 497. According to the above description, due to the conductive line 30 a, 30 b, 30 c, 40 a, 40 b or 40 c of the display 430 designed to avoid the lens 497 or not to overlap with the lens 497, the amount of received light and the angle of view of the lens 497 may be secured.

FIG. 8A is a perspective diagram illustrating a rear surface 4002 of an example electronic device according to an embodiment. FIG. 8B is a sectional view taken along line B-B′ of FIG. 8A.

FIGS. 8A and 8B, the camera device 490 may be located at a second position P2 on the multi joint rail 468 arranged on the inner support member 461 when the electronic device 400 (or the first structure (410 of FIG. 6)) is in the open state. For example, when the first structure 410 is transitioned into the open state by the movement of the second structure (420 of FIG. 6) in the direction{circle around (1)}, the second position P2 may be spaced apart from the first position P1 described above by the movement distance. In this regard, when the second structure 420 moves in the direction{circle around (1)} in order to transition the first structure 410 into the open state, the inner support member 461 may move in the direction of movement of the second structure 420. Accordingly, the multi-joint rail 468 arranged in one area of the inner support member 461 may be pulled in the direction of movement of the second structure 420, and the camera device 490 may be relatively positioned on the multi joint rail 468 in accordance with the traction of the multi-joint rail 468 to be positioned at the second position P2. The traction of the multi-joint rail 468 may rotate the gear 493 of the camera device 490 engaged with the multi-joint rail 468 to rotate the camera module 495 fastened to the gear 493, so that the position of the lens 497 of the camera module 495 may be changed. For example, the lens 497 of the camera module 495 may be positioned to face the rear surface 4002 of the electronic device 400. To this end, the gear 493 may be designed to have a corresponding periphery or rotation amount such that the lens 497, which faces the front surface (4001 of FIG. 7A) of the electronic device 400 at the first position P1, faces the rear surface 4002 of the electronic device 400 at the second position P2.

In an embodiment, at least one component (e.g., the second plate (421 of FIG. 4) and/or the window cover (450 of FIG. 4)) arranged under the camera device 490 at the second position P2 may include an aperture for supporting the angle of view of the camera module 495 (e.g., the aperture (422 of FIG. 4) formed in the second plate 421, the aperture 453 formed in the window cover 450, or the like). In various embodiments, the aperture (453 of FIG. 4) of the window cover 450 arranged at the lowermost portion of the camera device 490 at the second position P2 may be substantially shielded by a transparent window 454.

FIG. 9A is a diagram illustrating a first operation example of an example electronic device according to an embodiment. FIG. 9B is a flowchart illustrating an example operating process 900 b of an electronic device related to the first operation example according to an embodiment.

According to an embodiment, the electronic device 400 may be electrically or functionally connected to the above-described camera device (490 of FIG. 5A or FIG. 5B), and may include at least one processor (e.g., a processor (e.g., including processing circuitry) 1020 of FIG. 10) that performs control or data processing concerned with the functional operation of the camera device 490. In an embodiment, the processor may control the operation of the camera device 490 based on the open and closed states of the electronic device 400. In this regard, for example, the position information of the camera device 490 and/or the second structure (120 of FIG. 1A) according to each of the open and closed states of the electronic device 400 may be stored in the memory (e.g., the memory 1030 of FIG. 10) of the electronic device 400.

Referring to FIGS. 9A and 9B, in operation 901, the processor of electronic device 400 may determine a position change of the camera device 490. In this regard, a first sensor (e.g., an acceleration sensor, a gyro sensor, or the like) configured to sense the position of the camera device 490 may be included in one area of the camera device 490.

When it is determined that the position of the camera device 490 is changed based on the position information provided from the first sensor, in operation 903, the processor may determine an area change of the front display area 4111 of the electronic device 400. In an embodiment, the area change determination of the front display area 4111 may be based on the position information of the second structure 120. In this regard, a second sensor (e.g., a position sensor or the like) configured to sense the movement of the second structure 120 may be included in one area of the second structure 120. The processor may determine whether the electronic device 400 is in the open or closed state by the movement of the second structure 120 based on the position information provided from the second sensor. In an embodiment, when the electronic device 400 is transitioned from the closed state to the open state by external force, the processor may determine that the area of the front display area 4111 is expanded and the lens (497 of FIG. 6) of the camera device 490 faces toward the rear (or the second structure 120) of the electronic device 400. Alternatively, when the electronic device 400 is transitioned from the open state to the closed state, the processor may determine that the area of the front display area 4111 is reduced and the lens 497 of the camera device 490 faces toward the front (or the first structure (110 of FIG. 1A)) of the electronic device 400.

In operation 905, the processor may change the resolution of the display (e.g., the display device 1060 of FIG. 10) of the electronic device 400 in accordance with the area change of the front display area 4111. For example, the processor may set or manage the pixels included in the front display area 4111 whose area has been changed, or change the configuration (e.g., the density (dpi) or total size of the screen, and the like) of the screen to be displayed through the front display area 4111 whose area is changed.

In operation 907, the processor may control the driving of the camera device 490 corresponding to the determined open or closed state of the electronic device 400 (or, the determined area of the front display area 4111). For example, when the electronic device 400 is transitioned from the closed state to the open state in operation 903 and it is determined that the lens 497 of the camera device 490 faces toward the rear of the electronic device 400, the processor may control the driving of the camera device 490 to activate the image photographing function for the rear (e.g. a still image, a video, or the like). In this operation, the processor may switch a first screen 50 (e.g., a home screen of the electronic device 400) displayed on the front display area 4111 when the electronic device 400 is in the closed state to an image photographing screen 60. When the electronic device 400 is transitioned from the open state to the closed state again, the processor may control the operation of the camera device 490 to deactivate the image photographing function and switch the image photographing screen 60 displayed on the front display area 4111 to the previous first screen 50.

FIG. 9C is a diagram illustrating a second operation example of an example electronic device according to an embodiment. FIG. 9D is a flowchart illustrating an operation process 900 d of the electronic device related to the second operation example according to an embodiment. The operations described with reference to FIG. 9D may be performed at least partially the same as or similar to the operations described with reference to FIG. 9B, and redundant descriptions may not be repeated below.

Referring to FIGS. 9C and 9D, in operation 909, the processor of the electronic device 400 may determine whether a call is received from an external device. According to an embodiment, the call may relate to a video call function using the camera device (490 of FIG. 5A or 5B) mounted on the electronic device 400.

When it is determined that the call is received, in operation 911, the processor may determine whether the position of the camera device 490 is changed. For example, the processor may receive the position information of the camera device 490 from the first sensor (e.g., an acceleration sensor, a gyro sensor, or the like) included in one area of the camera device 490 to determine whether the position of the camera device 490 is changed.

When it is determined that the position of the camera device 490 is changed, in operation 913, the processor may determine whether the area of the front display area 4111 of the electronic device 400 is changed. In this regard, the processor may obtain the positional information of the second structure 120 from the second sensor (e.g., a position sensor, or the like) included in the second structure (120 of FIG. 1A) of the electronic device 400, and may determine whether the electronic device 400 is in the open or closed state by the movement of the second structure 120, based on the position information. In an embodiment, when it is determined that the electronic device 400 is in the open state, the area of the front display area 4111 may be expanded and the processor may determine that the lens (497 of FIG. 6) of the camera device 490 faces toward the rear of the electronic device 400. Alternatively, when the electronic device 400 is determined to be in the closed state, the area of the front display area 4111 may be reduced and the processor may determine that the lens 497 of the camera device 490 faces toward the front of the electronic device 400.

In operation 913, the processor may change the resolution of the display (e.g., the display device 1060 of FIG. 10) of the electronic device 400 corresponding to the area change of the front display area 4111.

In operation 917, the processor may control the driving of the camera device 490 in response to the determined open or closed state of the electronic device 400 (or the determined area of the front display area 4111). For example, when the call is received, when it is determined that the electronic device 400 is transitioned from the open state to the closed state such that the camera device 490 faces toward the front of the electronic device 400 (or the first structure (110 of FIG. 1A)), the processor may control the driving of the camera device 490 to activate the function of photographing an image in the forward direction. In this operation, when the electronic device 400 is in the open state, the processor may switch a first screen 70 (e.g., a video call receiving screen) related to the call reception displayed through the front display area 4111 to a video call screen 80 for photographing at least a part of a user located in front of the electronic device 400.

FIG. 9E is a diagram illustrating a third operation example of an example electronic device according to an embodiment. FIG. 9F is a flowchart illustrating an operation process 900f of an electronic device related to the third operation example according to an embodiment. The operations described with reference to FIG. 9F may be performed at least partially the same as or similar to the operations described with reference to FIG. 9B, and redundant descriptions may not be repeated below.

Referring to FIGS. 9E and 9F, in operation 919, the processor of the electronic device 400 may determine the photographing function (or the photographing mode) of the camera device (490 in FIG. 5A or 5B) which is being operated. According to an embodiment, the photographing function of the camera device 490 may be determined as a selfie photographing function related to the photographing of the front of the electronic device 400 or a landscape photographing function related to the photographing of the rear of the electronic device 400, or the like, but is not limited thereto.

In operation 921, the processor may determine a position change of the camera device 490. For example, based on the position information of the camera device 490 provided from the first sensor (e.g., an acceleration sensor, a gyro sensor, or the like) included in one area of the camera device 490, the processor may determine the position change of the camera device 490.

When it is determined that the position of the camera device 490 is changed, in operation 923, the processor may determine the change in the area of the front display area 4111 of the electronic device 400. In this regard, the processor may obtain the position information of the second structure 120 from the second sensor (e.g., a position sensor, or the like) included in the second structure (120 of FIG. 1A) of the electronic device 400, and may determine whether the electronic device 400 is in the open or closed state due to the motion of the second structure 120, based on the obtained position information. In an embodiment, when the electronic device 400 is determined to be in the closed state, the area of the front display area 4111 may be reduced and the processor may determine that the lens (497 of FIG. 6) of the camera device 490 faces toward the front of the electronic device 400.
